Roll forming, also spelled rollforming, is a continuous bending operation in which a long strip of sheet metal (typically coiled steel) is passed through sets of rolls mounted on consecutive stands, each set performing only an incremental part of the bend, until the desired cross-section profile is obtained. Roll forming is ideal for producing constant-profile parts with long lengths and in large quantities.
Famous quotes containing the words roll and/or forming:
“Lord, what a thoughtless wretch was I,
To mourn, and murmur and repine,
To see the wicked placed on high,
In pride and robes of honor shine.
But oh, their end, their dreadful end,
Thy sanctuary taught me so,
On slipp’ry rocks I see them stand,
And fiery billows roll below.”
—Isaac Watts (1674–1748)
“Then Moses stretched out his hand over the sea. The LORD drove the sea back by a strong east wind all night, and turned the sea into dry land; and the waters were divided. The Israelites went into the sea on dry ground, the waters forming a wall for them on their right and on their left.”
—Bible: Hebrew, Exodus 14:21,22.
